Weight loss questions

I'm sitting at my internship and it's state testing week so I can't meet with any of my students or run my groups until this afternoon after lunch. Instead, I've been outlining my group activities and pretty much twiddling my thumbs because I've been bored out of my mind.

My mind keeps wandering because I was logged into my e-mail and I started thinking about my workout last night. I spent two hours at the gym, which wasn't intentional. I did some warm up stretches, about 45 minutes of cardio because New Moon was showing in the cardio theater, some free weights with Denise, and then some cool down stretches.

It doesn't seem to matter how often I work out, my weight either stays right where it is or goes down maybe a pound or two. Last month I lost three pounds, which for me I thought was good because the month before I hadn't lost anything and I had even gone on vacation before this weigh in. However, when I posted it on facebook in the midst of my excitment, my cousin made a comment that it's not the pounds that matter, but the inches.

First off, I don't think I've ever measured myself. Second, if the pounds don't matter in your weight loss, then why even have a chart showing whether you're overweight, average, etc? It's been so discouraging lately to get excited about a change in the scale just to have people tell me that only the inches matter and not the pounds.

So I guess my question for my health conscious friends out there-how do I lose the inches? I do know that no matter how much I lose, my pants size has not moved very far. The current size I'm in now is too loose, but the size down is too small and it's been this way for like six months and I don't know what else to do to lose.

I've changed my workouts up and have started mixing in classes with my regular workouts because my boss told me that would help. I've been portioning out my foods so I'm not overeating and I've even been changing what I eat but yet nothing is working. I don't eat as much as I used to now because for one, it's getting warmer out and when it's warm outside I don't eat much and second, I just haven't been hungry. I'm starting to get frustrated and I'm about ready to throw in the towel. I love my workouts, but apparently I'm not seeing much progress. Help anyone?
